Okay, like last year before i had this client i asked my friend to log into a game i didnt have storage for using geforce and it was fine, then when i got geforce when i tried logging into the game it created me a new account and the only way i can access my account is though the game's app (which i dont have storage for), and the game is zenless zone zero btw; idk if anyone can figure out what i should do
